Comments about this movie

53 minute Children's Film Foundation adventure with standard plot of 4 scratty kids foil a dastardly plot by evil villains, taken from a CCF/BFi box set I'm ploughing through to help pass lockdown. Location not given on packaging or imdb - film wants to suggest Didbury/Didsbury

... but I think it's probably Surrey or nearby from many number plates.

The timing of this film caught a fair proportion of pre WW2 cars still in daily use, many of which dragged themselves around Britain for a few years more until the introduction of the “Ten year test”, soon to be the three year test. My Dad got rid of his Citroën traction avant which was by then about 15 years old and bought a new Morris Cowley in October 55. Entry to the Grammar School in 1958 produced a teachers’ car park containing a newish Oxford belonging to the headmaster, a Hawk for his deputy, sliding down to the French master’s 1936 Morris Eight and the woodwork man’s BSA 500 and Watsonian chair.
